Write a program using a float array (10 elements maximum) that allows a user to find the mean (), standard deviation (), and variance ( 2 ) of data points entered. The sample standard deviation model is used. The mean is equivalent to the average value of the data and is denoted . Each data point or sample is , of which there are samples total. The formula to find the standard deviation is: = ( ) 2 =1 1 In words, you need to find the sum of the difference between each point and the mean squared.
